Flutter，如何删除对话框周围的空格? [英] Flutter, How to remove white spaces around dialog box?

问题描述

我在从服务器获取数据时调用此对话框.此对话框周围有空格.我可以删除对话框周围的这个空白区域.这是我的代码.

I am calling this dialog while getting data from server. This dialog box is having white spaces around it. I can I remove this white space around my dialog box. Here is my code.

var bodyProgress = new Container(
 decoration: new BoxDecoration(
  color: Colors.blue[200],
  borderRadius: new BorderRadius.circular(10.0)
 ),
width: 300.0,
height: 200.0,
//color: Colors.blue,
alignment: AlignmentDirectional.center,
child: new Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
  new Center(
    child: new SizedBox(
      height: 50.0,
      width: 50.0,
      child: new CircularProgressIndicator(
        value: null,
        strokeWidth: 7.0,
      ),
    ),
  ),
  new Container(
    margin: const EdgeInsets.only(top: 25.0),
    child: new Center(
      child: new Text(
        "Signing up...",
        style: new TextStyle(
            color: Colors.white
           ),
         ),
       ),
     ),
   ],
  ),
);

我在这里调用这个对话框.我已经尝试过 AlertDialog() 和 SimpleDialog() 两者都有相同的问题.

Here I am calling this dialog. I've tried with both AlertDialog() and SimpleDialog() having same issue with both.

showDialog(context: context, child: new AlertDialog(
  content: bodyProgress,

));
